MEMOIRS OF THE ^'EW YORK BOTANICAL GARDEN 



Tabebuia suberosa 



(Fruiting specimens.) Branchlets short and thick, gray, ex- 

 ceeclingly rough from crowded concave scars Avith thick corky 

 margins. Petioles 5 to 10 cm. long, slender, grooved. Leaflets 

 5, the petiolules 2.5 to 5 cm. long, similar to the petioles. Blades 

 6 to 12 cm. long, 3 to 6 cm. broad, elliptic with rounded summit 

 and base, the latter mostly a little inequilateral; irregularly 

 sinuate-dentate, thick and rigid, finely papillose on both sur- 

 faces, drying brownish, the venation lightly prominent beneath, 

 coarsely reticulate, the secondaries 8 or 10 on a side, crooked, 

 Avidely spreading, connecting at some distance from the margin. 

 Fruits racemose, the peduncles and pedicels very stout, deeply 

 annulate-fissured. Follicles about 1.5 dm. long, 1.5 to 2 cm. 

 broad as pressed, oblanceolate, obtuse, finely papillose. Seeds 

 about 4 cm. long, including the Aving, the seed body about 2 cm. 

 long, and nearly as Avide, the Aving coarsely fimbriate. 



On the pampas near Lake Kogagua, Boli\ia, 1,000 feet, H. H. 

 Rushy, November 3, 1921 {no. 1423). A common tree, of 

 crooked, stunted growth, occasionally 25 to 30 feet high, the bark 

 excessiA^ely corky-roughened, the Avood light and brittle and used 

 for rafts. KnoAvn as "cork-tree." 



The above is the type, but another specimen, collected in 

 floAver, appears to be the same. The leaA^es are about two thirds 

 as large. Pedicels slender, 1 cm. long, abruptly enlarged at the 

 summit. Cah'x 1.5 cm. long, 1 cm. broad, turbinate-campanulate, 

 the mouth as in the type. Corolla 6 or 7 cm. long, the tube 

 nearly 1.5 cm. Avide, as pressed, many-nerA^ed, yelloAv. 



Trinidad, 700 feet, 3/. Cardenas, March 7, 1922 {no. 26, 

 special). "Common tree of pampas, groAving to 9 feet, Avith yel- 

 loAv floAvers. The bark is different from the one that groAvs about 

 Lake Kogagua." I should regard it as a mere A^ariety of T. 

 suberosa. 



Geskeriaceae 

 Nautilocalyx Whitei 



Pilose or subtomentose, except the upper leaf-surfaces. 

 Stems thick but Aveak, a foot or tAvo long, prostrate and rooting, 

 at least at the base, more or less angled or sulcate. Leaves 

 croAvded at the summit, the inflorescence densely croAvded among 

 their bases. LeaA^es 15 to 25 cm. long, 3 to 5 cm. broad, lanceo-
